The present disclosure provides an inkjet ink and primer fluid set containing an aqueous primer composition and aqueous inkjet inks. At least one of the inks contains a first pigment dispersion and a second pigment dispersion. The first pigment dispersion forms an aggregation with the primer composition whereas the second pigment dispersion does not form an aggregation with the primer composition.

The present disclosure provides an inkjet ink and primer fluid set containing an aqueous primer composition and aqueous inkjet inks. The aqueous primer composition forms a coating on a print substrate. The inkjet inks contain a polymeric binder that interacts with the primer composition. This fluid set is particularly suitable for printing on non-porous plastic substrate.

An ink set according to the present disclosure includes: a treatment liquid containing an aggregating agent; a deep ink composition; and a light ink composition, the ink compositions containing colorants, belonging to the same color system, and each being a water-based ink jet ink, the light ink composition contains an organic solvent which is a condensate of an alkanediol having 2 or 3 carbon atoms and which has two hydroxy groups, and the deep ink composition contains an organic solvent which is an alkanediol having 2 to 4 carbon atoms.

A liquid composition includes an inorganic particle and a multivalent metal salt, wherein the liquid composition has a tacking force of 50 mN or less in an area of cast-coated paper where the liquid composition is applied in an amount of 0.12 mg/cm.sup.2 for the cast-coated paper followed by heating at 80 degrees C. for 15 seconds.

Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.
